Download Information on Engine Misfire MIL/SES Light Illuminated or Flashing DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P0420 or P0430. SERVICE INFORMATION If you encounter vehicles that exhibit the above conditions, refer to SI for the appropriate DTC(s) set. If no trouble is found, the cause may be due to an ECM ground terminal that has corroded with rust over time. Inspect the main engine wiring harness ground terminal (G103) for this condition. The wire terminal (G103) attaches either to the front or to the rear of the right side cylinder head, depending on the model year of the Full Size Pickup and/or Utility Trucks. If the ECM ground terminal has been found to be corroded, then follow the service procedure outlined in this bulletin to correct the corrosion issue.

Download 1996 Chevrolet Chevy K Pickup – 4WD | Chevy Pickup, GMC Pickup, Suburban, Tahoe, Yukon (VIN C/K) Service Manual DTC P1351 Ignition Coil Control Circuit High Voltage. Circuit Description The enhanced ignition system uses the crank sensor in order to provide the timing input to the VCM. The VCM uses this reference pulse in order to determine the individual ignition spark timing for each cylinder. Once the VCM calculates the ignition timing, the ignition coil module on the IC circuit receives the timing signal. Each timing pulse received by the ignition coil module on the IC circuit triggers the coil module in order to operate the ignition coil. The secondary ignition voltage is induced, and then the secondary ignition voltage is sent to the distributor for distribution to each spark plug. This DTC is a type A DTC. The IC signal voltage ranges from about 0.5 volt to 4.5 volts.… Read More

Download 1. Remove the door panel. Refer to section 20 of the 1996-00 Civic Service Manual. 2. Remove the armrest bracket, then pull down the plastic cover to gain access to the window regulator. 3. Carefully move the glass until you can see the glass mounting bolts, then loosen them. Slide the guide rearward, remove the glass from the guide, and carefully pull the glass out through the window slot. 4. Check the year and VIN. If the vehicle is a 1996 or 1997 within the affected VIN range, replace the window regulator. Go to step 5. If the vehicle is not a 1996 or 1997 within the affected VIN range, go to step 8. 5. Remove the two roller guide bolts and the two rear regulator mounting bolts; then remove the front regulator mounting bolts. 6. Disconnect the power window motor connector, and detach the harness clip (if applicable); then lift and remove the regulator through the opening in the door.… Read More

Seville/STS/DeVille Any other GM Vehicles with the VATS or PASSKey II system (If your ignition key looks like the one pictured below.) Alright, let’s begin the madness: 1. Take your DMM, set it to measure Ohms (use the 20k setting.) Measure the resistance across the pellet of the ignition key. Place one probe on the silver part of one side of the pellet, and the other probe on the other side. Write this value down. 2. Purchase a resistor or resistors that add up to the value measured in step 1. Radio Shack is a great place to go for the resistors, heat shrink tubing, and the “bullet-style” solderless connectors.… Read More
